I was trying to put a metal reciever on my Kraken and noticed a little irregularity that made it quite difficult. The thing under the fire selector where the screw goes in actually sticks out a few millimeters and makes the old body basically impossible to get off and, I imagine, the new one practically impossible to get on. I did watch the videos on mechbox.com, and the AKs they show don't seem to have this feature; has anybody encountered this before and do you know how to get around it?

Thanks!
